Abstract

A vehicle headlamp includes a light source, an optical projection element, a light deflector, and a tubular housing. The optical projection element projects light incident on the projection optical element forward. The light deflector includes a plurality of optical devices that are lined up. The optical devices are individually switchable between a first state and a second state. In the first state, the optical devices reflect light emitted from the light source in a direction other than a direction toward the projection optical element. In the second state, the optical devices reflect the light emitted from the light source toward the projection optical element. The light deflector is disposed within the housing. The optical projection element is arranged in an opening section of the housing. A first portion of the housing, which intersects a beam path of a light beam incident on the light deflector, is transparent.

Description

  • BACKGROUND
  • Field of the invention
  • Exemplary embodiments relate to a vehicle headlamp that uses a light deflector.
  • Relevant technology
  • A light deflector is provided with a large number of micromirror devices, each of which is tiltable. Tilt angles of the micro-mirror devices are digitally switched between a first tilt angle and a second tilt angle so that a reflection direction of light from a light source fits between a first reflection direction (that is, the micro-mirror devices are turned ON) and a second reflection direction (that is, the micro-mirror devices are switched off) can be changed.
  • JP H09-104288 A (equivalent to US 5,938,319 A ) describes a vehicle lighting device including a reflective light deflector disposed on a beam path of reflected light from at least one light source. The light deflector may reflect light that strikes the light deflector so that a luminous flux emitted from the light apparatus is formed.
  • PRESENTATION OF THE INVENTION
  • In a lamp unit using a light deflector such as one described above, the light deflector and the light source such as a light emitting diode are disposed in the same housing. In this configuration, air convection tends to occur near a surface of the light deflector due to heat generated by the light source. Dust and mobile substances, etc. carried by the air may adhere to the surface of the light deflector, resulting in contamination of the surface of the light deflector. As a result, a light intensity can be reduced and / or a shadow can be formed in the light distribution pattern.
  • In view of the above circumstances, the invention has been created. Exemplary embodiments provide technology that prevents or reduces contamination from a surface of a light deflector within a vehicle headlamp.
  • According to a feature of the invention, a vehicle headlamp includes a light source, an optical projection member, a light deflector and a tubular housing. The optical projection element projects light which impinges on the optical projection element to the front. The light deflector includes a plurality of optical devices which are strung together. The optical devices are individually switchable between a first state and a second state. In the first state, the optical devices reflect light emitted from the light source in a direction other than a direction toward the projection optical element. In the second state, the optical devices reflect the emitted light toward the projection optical element. The light deflector is disposed within the housing. The optical projection element is arranged in an opening section of the housing. A first portion of the housing that intersects a trajectory of a light beam incident on the light deflector is transparent.
  • With this configuration, since the case shields the light deflector from the light source, which is a heat generation source, air convection near the surface of the light deflector is avoided. As a result, contamination of the surface of the light deflector due to adhesion of dust or mobile substances thereto can be avoided and / or reduced.
  • The exemplary embodiment may prevent or reduce fouling of a surface of a light deflector within a vehicle headlamp.
  • BRIEF FIGURE DESCRIPTION
  • 1 is a vertical sectional view illustrating the schematic structure of a vehicle headlamp according to an exemplary embodiment of the invention; and
  • 2 is a schematic sectional view of a Lichtablenkers.
  • LONG DESCRIPTION
  • 1 is a vertical sectional view, the schematic structure of a vehicle headlight 1 according to an exemplary embodiment of the invention. The vehicle headlight 1 is respectively disposed on the left and right sides at a front portion of a vehicle. It is noted that the left and right headlamps have substantially the same configuration except that a part of their components has a symmetrical structure relationship between each other in the left-right direction.
  • The vehicle headlight 1 includes a first housing 60 , which has a substantially cylindrical shape and is configured with an opening portion on its vehicle side. An optical projection element 50 is at the opening portion of the first housing 60 appropriate.
  • A light source 10 For example, a semiconductor light-emitting device such as an LED, LD (laser diode) or EL (electroluminescent) device, a light bulb, an incandescent lamp (a halogen lamp), a gas discharge lamp (a discharge lamp) and the like may be.
  • An optical reflection element 20 is designed to receive light from the light source 10 is emitted to a reflection surface of a light deflector 30 to steer. Examples of the optical reflection element 20 include a fixed photoconductive body and a reflection mirror having an inner surface serving as a predetermined reflection surface. In cases where the light coming from the light source 10 is emitted, directly to the reflection surface of the Lichtablenkers 30 can be directed, the optical reflection element 20 not be provided.
  • The light source 10 and the optical reflection element 20 are inside a second housing 70 accommodated. The second housing 70 is at a lower portion of the first housing 60 appropriate.
  • The light deflector 30 is on an optical axis of the projection optical element 50 arranged. The light deflector 30 is designed to reflect the light coming from the light source 10 is emitted, specifically to the optical projection element 50 to reflect. The light deflector 30 For example, a MEMS (Electro-Mechanical Microsystem) in which multiple micromirror devices are arranged in a row (matrix) manner.
  • 2 is a schematic sectional view of the Lichtablenkers 30 , The light deflector 30 contains a micromirror series 34 and a transparent cover member 36 , In the micromirror series 34 are several micromirror devices 32 arranged in the matrix form. The transparent cover element 36 is front (right side in 2 ) of reflection surfaces 32a the micromirror devices 32 arranged. Every micromirror device 32 has a substantially square shape. Every micromirror device 32 contains a rotary shaft 32b extending in a horizontal direction and substantially the micromirror devices 32 halved.
  • The micromirror devices 32 of the light deflector 30 are configured to be individually between a first state (OFF state, represented by dotted lines in FIG 2 ) and a second state (ON state, represented by solid lines in FIG 2 ) to switch. When the micromirror device 32 in the first state (OFF state), the light coming from the light source 10 is emitted in a direction other than a direction of the projection optical element 50 to reflect. When the micromirror device 32 in the second state (ON state), the light coming from the light source 10 is emitted to the optical projection element 50 to reflect.
  • 1 shows (i) light coming from the light deflector 30 is reflected when the micromirror devices 32 of the light deflector 30 in the first state (OFF state, represented by dotted lines in FIG 1 ), and (ii) light coming from the light deflector 30 is reflected when the micromirror devices 32 of the light deflector 30 in the second state (ON state, represented by solid lines in FIG 1 ) are. As described above, the light deflector 30 specifically change the light reflection direction.
  • The optical projection element 50 is formed, for example, by a free-form surface lens having a front surface and a back surface formed in a freeform surface shape. The optical projection element 50 A light source image, which is formed on a rear focal plane containing a rear focal point, projects onto a virtual vertical projection surface in front of the headlight unit as an inverted image. The optical projection element 50 is arranged so that the rear focal point of the optical projection element 50 on the optical axis of the vehicle headlight 1 and near the reflecting surfaces of the micromirror array 34 is positioned.
  • A controller 300 represents an emission intensity of the light source 10 and performs ON / OFF control for each of the micromirror devices 32 of the light deflector 30 by. The hardware configuration of the controller 300 can be realized by elements and circuits such as a computer CPU and memory. The software configuration of the controller can be realized by a computer program. The control 300 receives information, including vehicle speed information and vehicle attitude information, from an image processor 310 , a steering sensor 320 , a navigation system 300 , a light switch (not shown), a vehicle speed sensor (not shown) and an acceleration sensor (not shown) and like. The image processor 310 is with an imaging device 312 connected. The control 300 transmits various control signals to the light source 10 and the light deflector 30 according to the received information.
  • In the first case 60 is at least a section 62 transparent. The transparent section 62 of the first housing cuts a ray of light that hits the light deflector 30 from the reflection element 20 comes from. The transparent cutting section 62 can by fitting a transparent element such as glass or plastic resin in an opening portion, which previously in the first housing 60 is formed, be formed. Alternatively, the transparent cutting portion 62 produced by a known two-color forming process. In addition, it is preferable that an anti-reflection process such as an AR coating on the cutting section 62 is applied.
  • In the first case is a section 64 opaque and provided with a non-reflective coating. Light coming from the light deflector 30 reflected, hits the opaque section 64 of the first housing 60 when the micromirror devices 32 of the light deflector 30 in the first state (OFF state). This configuration is used to prevent light from the subarea 64 be reflected and projected in front of the headlamp unit when the micromirror devices 32 in the first state (OFF state). However, in reality, there is a case where light is directed to sections other than the opaque sections 64 differs. Therefore, it is preferable that the entire first housing 60 except the cutting section 62 , is opaque and that anti-reflective coating on the inner surfaces of the first housing 60 is applied.
  • As described above, the first housing insulates 60 the light deflector 30 in a different room than the light source 10 , which serves as a heat source. Therefore, air convection caused by heat moves from the light source 10 is generated, air within the first housing 60 which is the light deflector 30 not in it. Consequently, it can be avoided or reduced that the surface of the transparent cover member 36 of the light deflector becomes dirty due to adhesion of dust and / or mobile substances such as adhesive. Thus, it can be prevented that a light intensity of the vehicle headlamp is reduced and that a shadow is formed in the light distribution pattern. Moreover, it can be avoided if a desiccant or the like in the first housing 60 provided is that condensate on the surface of the transparent cover member 36 is formed.
  • It can act as a way to prevent pollution of the light deflector 30 be considered that only a periphery of a Lichtablenkers is covered with a transparent cover. However, a light beam in such a configuration passes the transparent cover twice; when the light beam is incident and when the light beam is emitted. Thus, losses of the luminous flux would be great. On the contrary, according to the exemplary embodiment, a light beam passes the transparent portion once.
  • The optical projection element 50 and the first case 60 may be formed integrally or in one piece. The configuration increases the airtightness of the first housing 60 so that it can be more reliably prevented that contaminants penetrate into the first housing from the outside. The first case 60 can with an opening portion, for example, between the transparent cutting portion 62 and the optical projection element 50 be educated.
  • The exemplary embodiments of the invention are described above. However, the invention is not limited thereto. Suitable combinations of configurations of the exemplary embodiments and those obtained by substituting part of the configurations of the exemplary embodiments with other elements are also included in the invention.
  • Moreover, (i) modifications to corresponding combinations in the exemplary embodiment, (ii) suitable changes in the sequence of processes in exemplary embodiments, (iii) various design changes in the exemplary embodiments, and the like, may be based on the knowledge of one skilled in the art. Embodiments obtained by such changes may also be included within the scope of the invention.
